Enable bits in the Status Byte to generate a Service Request. To enable
specific bits, you must write a decimal value which corresponds to the
binary-weighted sum of the bits in the register. The selected bits are
summarized in the “Master Summary” bit (bit 6) of the Status Byte Register.
If any of the selected bits change from “0” to “1”, a Service Request signal
is generated. The *SRE? query returns a decimal value which corresponds
to the binary-weighted sum of all bits enabled by the *SRE command.
Query the summary (status byte condition) register in this register group.
This command is similar to a Serial Poll but it is processed like any other
instrument command. This command returns the same result as a Serial Poll
but the “Master Summary” bit (bit 6) is not cleared by the *STB?
command.
Trigger e.g. a sweep, a burst, or a simple pulse from the remote interface
depending on the selected instrument function. It is similar to the :TRIG
command.
Performs a complete self-test of the instrument. Returns “+0” (PASS) or
“+1” (FAIL). If the test fails, one or more error messages will be generated
to provide additional information on the failure. Use the SYST:ERR?
command to read the error queue.
Wait for all pending operations to complete before executing any additional
commands over the interface.
